Identity of the mtDNA haplotype (s) of Phytophthora infestans in historical specimens from the Irish potato famine
KJ May, JB Ristaino - Mycological research, 2004 - Elsevier
The mtDNA haplotypes of the plant pathogen Phytophthora infestans present in dried potato
and tomato leaves from herbarium specimens collected during the Irish potato famine and
later in the 19th and early 20th century were identified. A 100 bp fragment of ribosomal DNA
(rDNA) specific for P. infestans was amplified from 90% of the specimens (n= 186),
confirming infection by P. infestans. Primers were designed that distinguish the extant
mtDNA haplotypes. 86% percent of the herbarium specimens from historic epidemics were …
